Differential access to life-saving COVID-19 vaccines reveals the inequitable distribution of wealth and power in the global system. While several countries have developed homegrown vaccines to avoid being priced out of markets dominated by transnational drug companies, Brazil—a country with a significant research and pharmaceutical base—lagged behind those of other middle-income countries. Why? This paper blends insights from dependency theory and the theory of global capitalism to demonstrate how political coalitions, leadership, and normative frameworks negatively affect state capacity and technological development. First, austerity in public investment in research, development, and innovation prior to and during the pandemic limited the amount of resources necessary to create homegrown vaccine candidates. Second, political leadership informed by science denialism did not prioritize the development of vaccines and even discouraged their use. The analysis of vaccine development in Brazil reveals that having a pharmaceutical base and strong leadership committed to scientific principles and backed by a political coalition seeking to expand social democratic rights play a vital role in developing treatments and responding to health crises.

This systematic review aims to give an overview of the diversity of research areas related to human biometeorology in Brazil. The main focus of this paper addresses research trends, represented by published papers with national and international authorship, main contributions and shortcomings, as well as challenges and prospects of research in this area of study. An extensive literature search was conducted in the Scopus, Web of Science, and Science Direct databases so as to identify relevant publication output up to July 2021 related to the research area. The screening resulted in 96 studies chosen for full-text reading. Overall, results indicated a reduced amount of articles on the subject matter published internationally, with noticeable gaps in research in some regions of the country, such as the Amazon region and in the Brazilian Midwest region. Research gaps in relevant areas have been identified with limited output in the climate dimensions of tourism, vector-borne diseases, mortality and morbidity in urban centers. Such gaps should further encourage researchers to engage in research focused on those areas. [ABSTRACT FROM AUTHOR]

Perspectives on the Environmental Implications of Sustainable Hydropower gathers scientific papers from three of the worlds most important hydropower producers to discuss aspects of sustainable hydropower and the means by which it can be studied and achieved. The papers examine the application and use of new technologies and protocols for studying hydropower, adaptive management and the implications and use of long-term data sets for minimizing hydropower impacts on fish populations. The papers include a cross section of biological and hydrological experts. The implicit among country comparisons highlight a number of common hydropower themes, particularly the need to expand from single species studies to include broader consideration of the ecosystem, the importance of maintaining habitat, trait and species diversity and the need for consistently collected long-term data sets.

The power system long-term expansion planning is a computer-intensive problem as demands a varied set of studies especially considering the increasing deployment of intermittent renewables. In the case of the Brazilian power sector planning, the responsible institutions mostly use proprietary software. This paper presents the multiyear two-stage academic generation and transmission expansion planning software, called CARTHER, developed by the authors in order to provide the academy an open-source and non-commercial software, with a friendly interface and with several applications for expansion planning of hydrothermal systems with high intermittent renewables penetration. CARTHER is then calibrated for a case study in the Brazilian power sector, considering the most recent governmental goals for renewable energies for the horizons of 2030, 2040, 2050 and 2060. The results demonstrate the functionality and the qualitative capacity of CARTHER optimization under the expansion's criteria of flexibility and reliability in the face of the intermittent renewables penetration.

The intermediate disturbance hypothesis (IDH) has been thoroughly investigated, but much controversy has been found for supporting its assumptions, which rely largely on the nature of the disturbance, spatial scale, and biological predictors tested. In this paper, richness of native and non-native species along a suite of Neotropical aquatic ecosystems across a broad latitudinal and geographical range was used to test the IDH predictions. An extensive literature survey was performed to compile native species richness and the occurrence of several taxonomic groups listed as non-native for twenty-four coastal rivers and bays evenly distributed into three climatic zones (tropical, transitional, and subtropical). The climatic gradient was confirmed by NMDS and PERMANOVA, but IDH predictions were only significantly supported for native and total species richness in the coastal bays. The distribution patterns of non-native marine species showed a linear instead unimodal pattern of increase with latitudinal climatic gradient, but the responses are complex and dependent of many non-exclusive factors, such as the sampling effort per ecosystem and the potential interference of other disturbance gradients that should be further addressed to unravel the role of IDH for non-native species distribution.

Clayey veins may develop in areas of hydrothermal activity by seepage of hot water through the soil and rock. In a slope located in Southern Brazil, such veins occur along the slip surface of some landslides. This paper aims to characterize this kind of clay and investigate its influence over the stability of that slope. An electro resistivity survey had been conducted to characterize the soil profile, and SPT boreholes were used to confirm geophysical data. An experimental laboratory campaign included the investigation of chemical, mineralogical, and geotechnical properties of these clay veins and the embedding residual soil. Drained shear strength of residual soil was measured through triaxial tests, and residual strength was measured for both materials using a ring shear apparatus. A series of limit equilibrium analyses were conducted to assess the role of clay veins on the slope stability. The geometrical discretization of veins is a difficult task, and an approach based on the assumption of overall shear strength is required to establish the operational shear strength parameters for this slope. A series of back analyses showed that failure surfaces consistent with those observed in the field were only reproduced when the adopted shear strength parameters of the soil mass were c' = 5 kPa and φ' = 20°. Considering the measured shear strength parameters of the hydrothermal clay c' = (0 and φ' = 8.5°) and the pattern in which the clay veins occur, it seems that they do not fully control the slope stability, but they significantly reduce the global cohesion and the average mass friction angle.

This paper provides an overview from the perspective of an invited international guest to the 15th Symposium of ANPEPP, held in Bento Gonçalves, Brazil, in May, 2014. ANPEPP, the acronym for "Associação Nacional de Pesquisa e Pós-Graduação em Psicologia," or the "Brazilian National Association for Research and Postgraduate Studies in Psychology" in English, is comprised of psychology faculty at postgraduate programs throughout Brazil. The theme of internationalization is especially relevant for Brazil, where there has been rapid development in science and technology output, affording it a new, emerging international role. The paper discusses the multiple connotations of internationalization, the goals for internationalization from different perspectives, and the impact of internationalization on psychological research and publishing in Brazil. It also addresses the opportunities and challenges of internationalization in Brazil and elsewhere. In addition, the author shares her experiences in the ANPEPP forum-plenary sessions and business meetings. Of particular note as a first-time attendee is the evaluation process for postgraduate education, conducted by CAPES, the Brazilian Federal Agency for Improvement of Higher Education. In closing, the author asks what psychology, as a discipline, can learn from ANPEPP's and Brazil's approach to developing and evaluating academic disciplines, and expresses appreciation for the opportunity to participate in what she characterizes as a unique convocation.

This paper analyzes the determinants of the self-reported income and food sufficiency in Brazil, highlighting how these subjective measures of wellbeing are affected by relative conditions. Analyses are based on pooled data from the 2002/2003 and 2008/2009 Brazilian Family Budget Survey and on estimates of the multinomial relation between income and food sufficiency with absolute and relative indicators. The paper highlights that living in a more affluent neighborhood does matter in self-reported perceptions of wellbeing. Stated income sufficiency depends positively on absolute family income and negatively on relative neighbor income. Moreover, neighborhood education and regional inequality affect both stated perceptions of income and food sufficiency. The paper concludes that improving personal income and education, as well as reducing inequality, is one of the most effective ways to improve both the quality of life and the general perceptions of wellbeing in society.

This paper considers the size of a farmer’s property as a key variable influencing land cover and land cover change in rural areas of developing countries. Data from 126 rural familial properties in the region around the city of Santarém, Pará, in the Brazilian Amazon, indicate that property size is important for understanding the trajectories of land cover change. Past research has focused on the distinction between small family farms and large capitalized farms, arguing that family farmers have a higher deforestation intensity, or on estimating the strength of the effect of property size relative to economic or demographic factors. This paper shows that larger familial properties are able both to retain a larger area in forest and to have long enough cycles of use and fallow to allow previously used land to become forested again. Based on these analyses and discussion, we argue that land use and land cover research must consider property size as an organizing principle in order to better comprehend the reciprocal relationship between population and environment in frontier areas of the Brazilian Amazon and other rural landscapes.

Indigenous peoples have been using fire in the cerrado (savannas) of Brazil as a form of management for thousands of years, yet we have little information on why, when and how these fire practices take place. The aim of this paper was to explore the traditional use of fire as a management tool by the Krahô indigenous group living in the north-eastern region of Tocantíns state, Brazil. The results indicate that the Krahô burn for a variety of reasons throughout the dry season, thereby producing a mosaic of burned and unburned patches in the landscape. The paper discusses this burning regime in the context of contemporary issues regarding fire management, and in the face of changing perceptions to fire by the Krahô themselves.

This article presents a brief overview of the history of psychology in Brazil. It highlights how the Brazilian Association of Research and Postgraduate Studies in Psychology (ANPEPP - Associação Nacional de Pesquisa e Pós-graduação em Psicologia) has fulfilled its mission of fostering discussion on scientific policy and stimulating interchange among researchers. First, it provides a retrospect of ANPEPP meetings, considering both: 1) the thematic working groups, which have served to bring together researchers, and to inspire the emergence of thematic associations and journals; 2) the discussion forums, which have contributed in the critical review of scientific policy, and the mission of postgraduate studies. Second, it focuses on the history of psychology in Brazil, from colonial times to the recent national commitment to postgraduate studies. The paper argues that the plans and strategies led by national funding agencies have been successful and that their results are evidenced by the role played by Brazil in the international arena, both in scientific production and the training of its researchers. By sustaining current policies, it seems certain that, even with the oscillations in the national economy, postgraduate education will grow steadily in its advance of the psychological sciences; and will be working towards a better quality of life, social justice and ecological sustainability.

An established body of literature documents current changes in rural livelihoods, agricultural practices, and agrobiodiversity patterns in smallholder communities across the globe. Contributing to this literature, this paper documents change in agricultural practices and agrobiodiversity patterns in a tidal floodplain settlement in Amapá, Brazil, where in recent years farmers increasingly devote their attention to the production of açaí fruits, an important regional crop with strong local, national and international markets. Research results indicate that farmers are abandoning subsistence production in annual fields to make room for açaí-dominated agroforests. At the same time, farmers are diversifying home gardens, and as a result conserve a portion of the crop diversity once maintained in annual fields in these areas. Agrobiodiversity documented in home gardens is much higher than previously recorded in the study area, and is equal or higher than previously reported in home gardens in other less-market integrated Amazonian communities. Research points to the need for innovative methods to document agrobiodiversity patterns in today’s modifying landscapes and for the historical analysis of such patterns to avoid presumptions that observed changes are unilateral and unidirectional.

An increasing number of developing and emerging economies have adopted an inflation targeting framework for monetary policy during the last two decades. This article investigates the politics of inflation targeting by focusing on the case of Brazil. I argue that the decision to implement an inflation targeting system in 1999 did not only reflect the concerns of political leaders with maintaining electoral support and external credibility. In addition, the choice of this new policy approach was informed by a shift in the technical consensus among Brazilian economists about the most effective way to tame inflationary pressures in a context of high capital mobility. The shift to inflation targeting thus reflected a process of social learning among technical elites, facilitated not only by the failure of the previous policy but also by the successful experience of other inflation targeting countries. Moreover, the evidence presented here suggests that, as the first country to adopt inflation targets in the context of an IMF-supported program, Brazil became a test case and a natural experiment for the redefinition of IMF conditionality and surveillance mechanisms. The paper thus sheds light on a process of reciprocal learning, whereby the IMF not only contributed to collective learning but also learned from the Brazilian case, subsequently becoming an active promoter of inflation targeting among developing countries.

The Brazilian biomes (Amazon, Atlantic Forest, Cerrado, Caatinga, Pantanal, and Pampa) comprise one of the highest levels of plant diversity in the world; however, non-sustainable practices, deforestation, and land use have resulted in significant losses and fragmentation of the native forests. These ecosystems are now threatened and protection of their native plants through ex situ conservation is an urgent necessity. Cryopreservation and in vitro conservation are complementary options for securing and protecting Brazil's native plant species because their potential economic value is critically important to develop strategies that will (1) support their sustainable utilization, (2) protect against the over-exploitation of species growing in natural habitats, and (3) conserve the genetic diversity of germplasm from species of different provenances. Biotechnological approaches will help to address future economic and environmental demands placed upon already at-risk species. Conserving seed germplasm ex situ provides an additional safeguard against the risks ( e.g., loss due to disease, climate change) of field conservation. Moreover, seed banks and cryobanks permit the long-term conservation of a wider genetic base; this offsets the labor and space intensive costs of conserving in the active growing state. This paper is a compilation of the current status of strategies applied for conserving Brazilian native plant species. [ABSTRACT FROM AUTHOR]

The paper presents the development of a decision support system for the management of geotechnical and environmental risks in oil pipelines using a geographical information system. The system covers a 48.5 km long section of the São Paulo to Brasília (OSBRA) oil pipeline, which crosses three municipalities in the northeast region of the São Paulo state (Brazil) and represents an area of 205.8 km. The spatial database was created using geo-processing procedures, surface and intrusive investigations and geotechnical reports. The risk assessment was based mainly on qualitative models (relative numeric weights and multicriteria decision analysis) and considered pluvial erosion, slope movements, soil corrosion and third party activities. The maps were produced at a scale of 1:10,000. [ABSTRACT FROM AUTHOR]

The aim of this paper was to validate the Brazilian-Portuguese version of the Satisfaction With Life Scale (SWLS), presenting evidence of its reliability and construct and criterion-related validity. A large Brazilian sample (2,180 participants), from five different populations (undergraduate and high school students, general population, elementary school teachers, and physicians), was considered. The results confirmed the single factorial structure and reliability (0.77 < Cronbach’s α < 0.88, mean α = 0.81) of the SWLS. Supporting its criterion-related validity, the SWLS correlated positively with positive affect and negatively with both negative affect and psychological distress across all five samples. The findings indicate that the Brazilian-Portuguese version of the SWLS is a valid instrument to use with diverse Brazilian samples. [ABSTRACT FROM AUTHOR]

The paper describes factors influencing artisanal fisheries at the São Francisco River in Brazil as an example of the challenges of managing socially and economically valued common-pool resource systems. A rapid assessment of problems affecting São Francisco River fisheries in 10 communities was carried out in 2003, representing the upper, middle, and lower river portions. Field visits, interviews, focus group discussions and a literature survey allowed us to map socioeconomic and environmental factors important to the fisheries, including conflicts and tensions between stakeholders. Federal, state, and municipal governments, industries, farmers, hydroelectric companies, and urban and rural populations all have a stake in river use. Traditional fishers are the most disadvantaged of these stakeholders. With declining fish populations, most of the fishing communities surveyed are now poor, socially excluded, and with few alternative livelihood options. The stakeholders involved in access and use conflicts are artisanal fishers, professional fishers, sport fishers, farmers, enforcement and regulatory agencies, and hydroelectric companies. Traditional fishers have close ties to the river and its environment and they are usually not invited to contribute to resource management decisions. We recommend changes to management structures involving the fishing communities that are essential to resolve the major conflicts and to improve equity and sustainability of artisanal fisheries.

Access to higher education in Brazil is to a large extent restricted to the higher socio-economic groups. Public universities have limited places and entry is determined by highly competitive exams, thereby excluding those who have not had a high quality secondary education or attended an expensive preparatory course. There has been considerable growth in the private sector to absorb the excess demand, but the majority of Brazilians cannot afford the fees. This paper develops a concept of equity in higher education in which, firstly, there should be sufficient places in the system as a whole and, secondly, all people should have a fair opportunity of attending the university of their choice regardless of socio-economic background. Recent efforts to expand access are analysed, including incentives for the growth of private universities, student loans and the new Prouni initiative, in which private institutions provide free places to low-income students in return for tax exemptions. While these initiatives have the potential to increase the total number of places, they will not lead to an equitable expansion, as disadvantaged students will still be confined to courses of lower quality or with lower subsequent value on the employment market. Initiatives aimed at the public sector such as the introduction of quotas and changes to entry examinations are also discussed. Finally, some implications for future policy development are outlined.

The production of reactive nitrogen worldwide has more than doubled in the last century because of human activities and population growth. Advances in our understanding of the nitrogen cycle and the impacts of anthropogenic activities on regional to global scales is largely hindered by the paucity of information about nitrogen inputs from human activities in fast-developing regions of the world such as the tropics. In this paper, we estimate nitrogen inputs and outputs in Brazil, which is the world’s largest tropical country. We determined that the N cycle is increasingly controlled by human activities rather than natural processes. Nitrogen inputs to Brazil from human activities practically doubled from 1995 to 2002, mostly because of nitrogen production through biological fixation in agricultural systems. This is in contrast to industrialized countries of the temperate zone, where fertilizer application and atmospheric deposition are the main sources of anthropogenic nitrogen. In Brazil, the production of soybean crops over an area of less than 20 million ha, was responsible for about 3.2 Tg N or close to one-third of the N inputs from anthropogenic sources in 2002. Moreover, cattle pastures account for almost 70% of the estimated 280×106 ha of agricultural land in Brazil and potentially fix significant amounts of N when well managed, further increasing the importance of biological nitrogen fixation in the nitrogen budget. Much of these anthropogenic inputs occur in the Brazilian savannah region ( Cerrado), while more urbanized regions such as the state of São Paulo also have high rates of nitrogenous fertilizer inputs. In the Amazon, rates of anthropogenic nitrogen inputs are relatively low, but continuing conversion of natural forests into cattle pasture or secondary forests potentially add a significant amount of new nitrogen to Brazil given the vast area of the region. Better measurements of biological fixation rates in Brazil are necessary for improving the nitrogen budgets, especially at a more refined spatial scale. [ABSTRACT FROM AUTHOR]

This paper questions the cultural neutrality of modernization and globalization policies that are imposed by major international monetary agencies. The authors propose that the structural adjustment policies imposed by the World Bank and International Monetary Fund are predominantly guided by the concept of developmental association. Guided by this concept, the dominant countries and agencies perceive all developing countries to be merely cultural variations of the same problem that assumes all countries require the same solutions. Through an analysis of the failures of World Bank programs in Brazil and other developing countries, the authors argue for greater recognition of the problems inherent in imposing cosmopolitan and global solutions on local contexts. The authors conclude that globalized solutions for local contexts are inappropriate when they are formulated out of ignorance of the local culture and context. [ABSTRACT FROM AUTHOR]

By definition, interest groups are seen as self-interested, that is, organizations established to pursue the self-interest of their members. As such, this plethora of self-interested actors has been seen largely as a negative thing, cluttering the policy process, creating unmanageable demands, and leading to “iron triangles” of interest group/legislative/bureaucratic networks geared toward funneling benefits to narrow groups. In contrast, social movements, nongovernmental organizations, and the like typically are seen as positive, democratizing players in public policy. This paper seeks to muddy both sides of this neat distinction by bringing the Brazilian third-sector literature and field research on scientific and professional associations in the states of Sergipe and Santa Catarina to bear on the question of the self- versus public-interested stance of third-sector groups. On the one hand, social movements can be just as self-interested as the more traditional interest groups. On the other, interest groups often act wholly in the public interest.

This paper describes the characteristics of acid rain in the Belo Horizonte Metro-politan Region/RMBH, Brazil, a region influenced by sulfur dioxide and nitrogen-oxides emitted by industries and automotive vehicles. The region also receives the prevailing winds from the large karstic area where an intensive calcareous exploitation occurs. Thesupply of alkaline calcareous dust to neutralize anthro-pogenic acids in the atmosphere can control the acidity of the RMBH precipitation. Rainfall was collected from 3 monitoring stations, on a daily basis, using bulk collectors, from October 1993 to February 1994. The volume-weighted mean pHs ranged from 4.98 to 5.27. Ca 2+ was the dominating ion followed by SO42 , NH4+ and NO3- . Acidity in precipitation was well correlated with SO42-:Ca 2+ and NO3-:Ca2+ ratios. In the dry periods, these calcium particles are continuously emitted to the atmo-sphere and as a result the acidity of the first rain that passesthrough this buffered atmosphere is lower. However, in a continuous rainy period the rain acidity tends to increase progressively. The results showed the great acid neutralizing capacity of the RMBH atmosphere by calcium particles.

This paper shows that the use of ethyl alcohol and sugar cane bagasse as fuel substitutions for gasoline, and natural gas, fuel oil or coal, can have an important role to avoid GHG emissions. The Brazilian Alcohol program and the use of sugar cane bagasse for generating electricity may prove to be an important alternative for the reduction of GHG emissions. Large-scale production and the use of renewable energy from biomass may qualify Brazil for recognition at an international level. It is shown that the cost of alcohol is higher than that of gasoline with the present low price of oil on the international market, but the costs could be reduced by feasible technological improvements.
